Overview
- Oaxaca health authorities confirmed two human cases linked to Cochliomyia hominivorax larvae in open wounds, involving men aged 48 and 76 with diabetes and graft‑healing complications, both treated and discharged.
- SINAVE reports 92 cumulative human cases as of November 28 across five states, with Chiapas accounting for 79 cases and 10 hospitalizations, and five deaths attributed to underlying conditions rather than the infestation itself.
- State and federal teams, including SENASICA and SEFADER, activated surveillance and containment measures and expanded community education on wound hygiene and early detection.
- The broader animal outbreak has reached 11,516 cumulative cases with 894 active foci as of early December, with the highest counts in Chiapas, Oaxaca and Veracruz and cattle as the most affected species.
- Industry group GCMA estimates the U.S. border closure to Mexican cattle since May 11 has cost about $1.3 billion and warns that insufficient 2026 funding for animal health could hinder control and market reopening.
